Holding a bouquet is an indispensable decoration for a wedding. There are many kinds of materials for holding flowers, such as roses, tulips, calla lilies and peony flowers, and there are many colors, such as wine red, pink, white or orange, which are basically used for weddings.
It's best not to open the bouquet at the wedding. There are two aspects. The first reason is that the meaning is not good. As I said before, bouquets are basically used at weddings, and it is not easy to send them open. The second reason is that holding flowers is usually tied. You open it and send it away. It's not so beautiful.
If it is a daily thing, it is not impossible to send flowers. For example, if you want to give your bouquet to your two best friends, you can divide it into two parts and give it to them respectively.
Regarding the bouquet at the wedding, you don't have to give it away. You can keep it as a souvenir, but you need to communicate with the MC in advance.
